RCBS built this two-die set to handle the massive case dimensions of the .50 BMG cartridge (brand part no. 30001), pairing a full-length sizer die with expander-decapping unit and a seater die with bullet seater plug. The set is cut with a 1-1/2-inch-12 thread to run on the AmmoMaster 2 press or the AmmoMaster Single Stage press fitted with the .50 BMG Conversion Kit, giving serious long-range and heavy-caliber handloaders a dedicated setup for one of the largest sporting cartridges reloaded today. For shooters standardized on RCBS equipment, this reloading die set is a direct path into .50 BMG handloading.
